weixin: getConfig json: %w

Error message

weixin: getConfig json: %w

What it means

getConfig calls ilink/bot/getconfig to fetch per-user context configuration (used to obtain the typing ticket) and decodes the body into getConfigResp. This error wraps a json.Unmarshal failure: the reply is not valid JSON or no longer matches the struct.

Solutions

1. Capture the raw body for inspection (add truncateForLog to the error)
2. Refresh the bot session/ticket and retry
3. Update getConfigResp to the current API schema
4. Eliminate intermediaries that replace JSON with HTML

if userID == "" || contextToken == "" { return errors.New("weixin: getConfig requires userID and contextToken") }

cfg, err := getConfig(ctx, userID, token)
if err != nil {
	if strings.Contains(err.Error(), "getConfig json") { refreshSession(); return retry() }
	return err
}

When it happens

Trigger: The getconfig endpoint returns non-JSON (HTML error page, empty/gateway body) or an iLink schema change breaks decoding into getConfigResp.

Common situations: Expired bot session causing an error page; proxy/WAF rewriting the body; WeChat iLink API protocol update.
